The LEAST SANDPIPER (Calidris minutilla) is the smallest shorebird, the definitive “peep”. An adult is only about 6″ long. They are to be found in pairs or groups, busily foraging in the sand and seaweed. Often they will mix in with other shorebirds. These birds nest in scrapes close to the water, with both parents involved in incubating the eggs. The female will usually leave the nest before the young birds fledge – perhaps (bizarrely?) sometimes even before the eggs hatch. Deal with it, male Least Sandpipers. Fortunately the hatchlings can feed themselves very soon, and are able to fly within two weeks of birth.
The “peep” call will no doubt be instantly familiar, although how to differentiate between the various types of sandpiper may be more of a problem… Here’s a short recording via Xeno-Canto (credit: Mike Nelson)
Not the feeblest punning title on this blog, but going hard for the avian-related booby prize. As it were. Many months ago I did a short post about these tiny plovers, and had begun to update it. Then I found that both the BNTand theABACO SCIENTIST are onto them too. Thanks to them, I have some excellent added material further down the page… But first, here’s a quick cut out ‘n’ keep summary
SIZECharadrius melodusis a Very Small Shorebird
HABITAT Rocky shores / sandy beaches; nesting in higher, drier areas of the shoreline where there is cover
RANGE From Canada (summer) down to the Gulf of Mexico (winter). They head south in August and return in March

CALLA thin whistled peep peeping, whether standing or flying, and a two-note alarm call [There are surprisingly few Piping Plover call samples online. Many sites – Audubon, eNature, Birdwatchers Digest – all seem to have the same one. So I’ll credit them all and the originator Lang Elliot and hope I’ve covered my back…]
BREEDING The male digs out several scrapes on the high shoreline. The female contemplates these efforts, and (if any meet her ideal domestic criteria) chooses her preferred one, which she then decorates (grass, weed, shells etc). Meanwhile, Mr Peep tries to impress her by chucking pebbles around, dive-bombing her, and strutting around her importantly and “fluffed up” [none of these tactics work in human courtship, in my experience]. If Mrs Peep (a) likes the home she has chosen and furnished and (b) has recovered from her fit of the giggles at all that performance, she permits mating to proceed
NESTING First nests normally have 4 eggs; later ones fewer. Both share incubation and subsequent parental ‘brooding’ duties
DEFENCE Plovers have a defensive “broken wing display” used to distract predators and draw attention away from the nest
THREATS Larger birds, cats, raccoons etc. Human disturbance. Plovers and chicks are vulnerable to storms & abnormal high tides
ZOOM…! Capable of running at astonishing speed over short distances. When they stop, they often snap the head back and forward.
STATUS Depending on area, treated either as Threatened or Endangered; IUCN listing NT
CONSERVATION Historically PP feathers were used as decoration in wealthy women’s hats – no longer a problem. Shoreline development and alterations to natural coastline are now the leading cause of population decline. This has been reversed through field and legislative protection programs, especially at nesting sites; public education; anti-predation measures; and restricting human access in vulnerable areas – including off-roading…
STOP PRESS Nov 18Sean has just posted a professional / scientific article about piping plovers, with some very useful information specific to Abaco and some helpful links, over at theABACO SCIENTIST. Clicking through is highly recommended if you want to know more about these little birds
This is the characteristic ‘pigeon-toed’ stance – they run that way too…
RICARDO JOHNSON’S 6 MINUTE VIDEO ‘PIPING PLOVERS’
Ricky is a well-known, infectiously enthusiastic, and compendiously knowledgeable Abaco nature guide (this guy gets way too much free publicity in this blog…). As I wrote when I originally posted it “In this video he focusses his binoculars on piping plovers, a threatened species of tiny plover which annually makes a long migration to the Bahamas, including Abaco – and then heads all the way north again.”
If this video doesn’t make you smile at some stage, I suspect a SOH bypass and / or your ‘anti-cute’ setting is jammed on. Even so you’ll see the differences between the piping plover and the more familiar Wilson’s plover.
The BNT / ABSCI material originates from the Audubon Society. If you want to know about the annual journeys of these little birds and where they are in each season, it’s all here. The item was made in conjunction with theESRI mapping project. I’ve put a screenshot below to give a general idea of what’s involved [click to enlarge] and you can reach the interactive Audubon page if you CLICKPIPING PLOVER
